Yeah that's my problem.
It's not theoretical. We had cases where someone had to go through 10+ DIMMs on a big machine in try and error to find out which one is wrong. Very bad situation.
[Double plus bad if it wasn't actually any of the DIMMs that were bad, but one of the VRMs on a big Opteron - it causes all the same symptoms as a bad DIMM :/]

I proposed something like that - best with an ASCII string ("First DIMM on the top left corner") But getting such stuff into BIOS is difficult and long winded.
